IIVIPROVED HEEL-POLISHING MACHINE.

Specification forming part of Letters Patent N o. 52,470. dated February6, 1866.

To all whom fit may concern:

Be it known that I, S. D. TRIPP, of Lynn, in the county of Essex andState of Massachusetts, have invented a new and useful ImprovementinMachines for Polishing the Heels of Boots and Shoes 5 and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, which will enable those skilled in the artto make and use thesame, reference being had to the accompanying drawings, forming part ofthis speciiication, in which- Figure 1 is an elevation of my invention;Fig. 2, a plan or top view of the same; Fig. 3, a vertical section ot' aportion of the same,

.taken in the line x x, Fig. 2.

shape under the action of the polishing-Wheel,

said difticulty being caused by the last having its center of motion outof line with the center ofthe heel, or not at right angles therewith,the hole in the last which receives the stud of the rotating arm being'bored in front of the center ofthe heel and slightly inclined towardAthe toc, in order to prevent splitting.

My invention consists in having the stud or studs which enter the lastarranged in such a manner that they, and consequently the last, may riseand fall, and thereby compensate for the oblique attachment of the lastto the rotating arm of the device.

A represents an upright, which is attached to a suitable base, B, andhas a shaft, C, passing horizontally through its upper end; with apolishing-wheel, D, at one end.

E is a guard or rest attached to the upright A, and against which thebottom of the heel of the boot or shoe is pressed while the heel isbeing polished.

F is a shaft,the lower end of which is iitted ina stop, a, on the base Bof the machine. The shaft is curved at its upper part, like a crank, andjust below said crank part there is a bearing, b, through which saidshaft passes.

To the upper end of the shaft F there is attached a socket, c, in whicha pendent plate,

springs attached to the shaft F, and having their upper ends bearingvagainst opposite sides of the plate G, as shown clearly in Fig. 3, saidsprings having a tendency to keep the plate G in a vertical position.

To one side of plate G there is attacheda horizontal arm or rod, f, onwhich a sleeve, g, is tted and allowed to turn freely, said sleeve gbeing provided with a pendant, h, atI its outer end, in which a stud,t', is inserted to enter the holes in the last AX. A supplemental stud,t', is attached to the arm or rod f, to enter the last a short distance.

By this arrangement it will be seen that the bottom of the heel of theboot or shoe may be kept in contact with the guard or rest E while theside of the heel is pressed against the polishing-wheel and the lastturned so that the wheel may act upon all parts of the heel, the plate Gbeing allowed to swing' or vibrate on its pivot d, so that the last mayrise and fall, and thereby compensate for the oblique attach ment of thelast to the sleeveeg. The turning of the shaft F on its bearings, itwill be seen, admits of the movement of the last and heel in ahorizontal direction.

The two studs are employed in order to prevent the turning of the lastindependently of the sleeve g. The heel may be pressed in contact withthe polishing-wheel by any suitable mechanical arrangement.

Having thus described myin vention, I claim as new and desire to secureby Letters Patent- 1. The attaching of the stud i, whichenters the holeor holes in the last A", to a sleeve, g, connected to a pendent orswinging plate, G, all arranged in such a manner as to admit of thelast, and consequently the heel of the boot or shoe, rising and fallingto admit of the proper adjustment of the h'eel to the polishing-wheeland guard or rest, substantially' as herein shown and described.

2. The springs e e, attached to the shaft F, in combination with thependent or swinging plate G, substantially as and for the purposespecied'.

3. The combination of the shaft F, pendent or swinging plate G, sleeveg, studs t' i', polishing-wheel D, and guard or rest E, substantially asand for the purpose set forth.
